DETAILED DESCRIPTION

The present invention relates generally cognitive video analysis and, more particularly, to a system and method for the overlaying video segments of the actions of audience members with video segments of an event performer during an event performance. Embodiments of the invention recognize that, although technology exists for measuring and analyzing audience reaction to video, there is no effective way to provide an overlay of video segments of audience reaction to portions of an event performance. Aspects of the invention are directed to mapping specific video segments of the actions of the event performer to specific video segments of the actions of the audience member(s) during a specified moment of the event, e.g., awards ceremonies, event presentations, product launches, stage performances, etc. In embodiments, while the event is occurring, cameras located around the venue of the event capture the actions of the event performer and the actions of the audience member(s). The actions captured by the cameras are stored in a video server for later retrieval and processing including but not limited to: identifying a participant in the event; identifying at least audience member having a social relationship with the participant; correlating facial expressions and/or gestures of the at least audience member to a moment involving the participant; and generating video content depicting the moment involving the participant overlaid with the correlated facial expressions and/or gestures of the at least audience member.

Aspects of the invention include retrieving video content of the event from a video server and metadata of the event. For example, a system may retrieve the full video content of an awards ceremony stored in the video server or retrieve portions of the video content of the awards ceremony stored in the video server. After retrieving the video content of the awards ceremony, the system may include analyzing event metadata and the video content to determine information about an event. For example, embodiments of the invention may analyze the metadata to determine that the type of the event is an awards ceremony and flag important moments in the awards ceremony such as the timing of presentation of the award, the seating arrangement of the awards ceremony, the location of the awards ceremony, along with other information about the awards ceremony.

Other aspects of the invention are directed to analyzing the video content to identify the event performer in the event and actions of the event performer at a specified moment in the event based on the metadata and the analysis the video content. Still other aspects are directed to analyzing the video content to identify audience member(s) of the event that have a relationship with the event performer. For example, after identifying the event performer based on the metadata and the analysis the video content, the system may identify audience member(s) that have a business relationship with the event performer based on the social network sites of the event performer. After identifying the audience member(s) that have a relationship with the event performer, the system may analyze the video content to identify actions of the audience member(s) at the specified moment in the event based on the metadata and the analysis the retrieved video content.

Still other aspects of the invention are directed to correlating the video content of the actions of the event performer at the specified moment to the video content of the actions of the audience member(s) at the specified moment. For example, during an awards ceremony, the system may correlate the video content of the actions of the event performer when receiving the award to the video content of the actions of the family members of the event performer when the presentation of the award occurs.

Other aspects of the invention include overlaying the video content of the actions of the event performer with the actions of the audience member(s) during the specified moment to generate a video still image. For example, during an awards ceremony, embodiments of the invention may overlay an image of the moment the award is presented to the event performer and images of the actions of the audience member(s) to the presentation of the award. The invention my then generate the video still image of the moment when the award is presented.

Other aspects of the invention include searching the video content for specific reactions of the audience member(s) during important moments in the event. For example, embodiments of the invention may search the video content for specific reactions of a family member of the event performer when the event performer gives a speech after being presented with the award.

FIG. 2 shows an exemplary environment in accordance with aspects of the invention. The environment includes an event processing device 60 which may be a computer system 12 of FIG. 1. In embodiments, the event processing device 60 includes a video retrieving module 62 that retrieves video content of the event from a video server 102 and event metadata, an event analysis module 80 that determines information about an event, a participant identification module 82 that identifies participants involved in the event, and a relationship determination module 84 that determines relationships between the participants involved in the event. The event processing device 60 may also include a video correlation module 86 that correlates video content of specific moments in the retrieved video content, a video overlay module 88 that overlays video content of specific moments over each other to generate a video still image, and a search module 90 that searches for specific moments in the retrieved video content. Each of the modules 62, 80, 82, 84, 86, 88, and 90 may comprise one or more program modules 42 as described with respect to FIG. 1. In embodiments, the event processing device 60 may include additional or fewer modules than those shown in FIG. 2. In embodiments, separate modules may be integrated into a single computing component or module. Additionally, or alternatively, a single module may be implemented as multiple computing components or modules.

Referring to FIG. 2, the event processing device 60 may be connected to a network 50 via the network adapter 20 of FIG. 1. The network 50 may be any suitable communication network or combination of networks, such as a local area network (LAN), a general wide area network (WAN), a public network (e.g., the Internet), a 3G network, a Long-Term Evolution (LTE) network, and/or 5G network.

The event processing device 60 may be configured as a special purpose computing device that is in communication with one or more cameras 92 a-n and the video server 102 over the network 50. The cameras 92 a-n may be digital cameras which may include one or more components of a computer system similar computer system 12 of FIG. 1, to store and process video information in a memory similar to memory 28 of FIG. 1. The cameras 92 a-n are represented as camera 92 a to camera 92 n, where n may be any appropriate number of separate cameras that provide video information to the video server 102 and the event processing device 60. In embodiments, the event processing device 60 may be a network subscriber's computer device, such as a laptop computer, smartphone, tablet, or other network device that has the ability to connect to the cameras 92 a-n and the video server 102 over the network 50.

Each camera 92 a-n comprise a video camera computer system configured to retain video content 94 of an event such as an awards ceremony, a performance, a contest, a presentation, etc. The video camera computer system of each camera 92 a-n may also be configured to retain metadata 96 of an event such as event location, event time, event venue, seating assignments of participants of the event, known participants in the event, among others. The video content 94 and the metadata 96 of the event may be transmitted over the network 50 to be stored in a video data store 106 of the video server 102. The video server 102 may also include a video processing module 104 that processes video content 94 and metadata 96 of the event recorded by the cameras 92 a-n. Additionally or alternatively, the computer system in the cameras 92 a-n may also process and store video content 94 and metadata 96 of the event. The video server 102 may be a computer system similar to computer system 12 in FIG. 1 where the video data store 106 corresponds to storage system 34 in FIG. 1 and where the video processing module 104 may corresponds to the program modules 42 in FIG. 1.

Still referring to FIG. 2, as noted above, the video retrieving module 62 is configured to retrieve stored video content of the event from the video server 102 and the event metadata from cameras 92 a-n. In aspects, a system may retrieve the full video content of the event stored in the video server 102 or retrieve portions of the video content of the event stored in the video server 102 based on the event analysis by the video retrieving module 62. For example, based on determining that the event is a business presentation, the video retrieving module 62 may retrieve video content of the entire businesses presentation. In another example, based on determining that the event is an awards ceremony, the video retrieving module 62 may retrieve portions of the video content of the awards ceremony. In this example, the video retrieving module 62 retrieves video content of the awards ceremony that encompasses only the video moments surrounding or near in time to the actual presentation of the award from the video server 102.

In accordance with aspects of the invention, the event analysis module 80 is configured to analyze event metadata and analyze the video content though a semantic analysis to determine information about an event used by the video retrieving module 62, such as determining the type of the event and determining important moments in the event. Semantic analysis of the video content of the event is rules based analysis may be used to assess and identify a type of event in the video content, i.e., to classify the event as one of a predefined type such as, for example, is an awards ceremony, a performance ceremony, a business presentation, product launch, etc. For example, based on the video retrieving module 62 retrieving the video content, the event analysis module 80 may analyze the metadata 96 and analyze the video content, using semantic analysis, to determine that the event is an awards ceremony. In some aspects, based on analysis of the metadata 96, the event analysis module 80 may flag or note the time of the presentation of the award to the instances event performer according to a schedule of the awards ceremony in the metadata 96. In other aspects, the event analysis module 80 may analyze the metadata 96 to determine a seating arrangement of the audience member(s) of the event. In other aspects, the event analysis module 80 may analyze the video content to determine location of the event, venue of the event, and setting of the event, among others.

In accordance with aspects of the invention, the participant identification module 82 is configured to analyze the video content to identify the event performer in the event based on the metadata 96 and a contextual analysis of the retrieved video content. The contextual analysis is an analysis of the video content that assesses the video content in terms of actions occurring in the video content. For example, based on the event analysis module 80 determining that the event is a business presentation, the participant identification module 82 analyzes the metadata 96 and the video content according to the contextual analysis process to identify the event performer as the individual giving the business presentation. In another example, based on the event analysis module 80 determining that the event is an awards ceremony, the participant identification module 82 analyzes the metadata 96 and the video content according to the contextual analysis process to identify the event performer as an individual in the video content receiving the award. In embodiments, the participant identification module 82 is also configured to determine an identity of the event performer. For example, the participant identification module 82 may analyze the event metadata to determine a name of the individual scheduled to receive an award, or the name of the individual giving a product launch presentation.

In embodiments, the participant identification module 82 is configured to analyze the video content to determine actions of the event performer at a moment in the event based on the metadata 96 and the analysis of the video content. For example, based on the event analysis module 80 determining that the event is an awards ceremony, the participant identification module 82 analyzes the metadata 96 and the video content according to the contextual analysis process to determine actions of the event performer at the moment the award is presented.

In other aspects, the participant identification module 82 is configured to analyze the video content to identify one or more audience members in the video content that have a social relationship with the identified event performer. The determining of the relationship may be a comparison of the video content of the audience members to photographs in the social network sites 98 of the event performer. For example, based on the participant identification module 82 identifying the event performer, the participant relationship module 84 accesses the social network sites 98 of the event performer, and uses computer-based facial recognition techniques to compare images of individuals at the social network sites 98 of the event performer to images of the audience members at the event. Based on this comparison, the participant relationship module 84 is able to determine if any of the audience members at the event are also people shown in images on the social network sites 98 of the event performer. In embodiments, any such audience member is deemed to have a social relationship with the event performer.

In other aspects, the participant identification module 82 is configured to analyze the video content to determine actions of the identified audience members at a moment in the video content of the event based on the metadata 96, the analysis of the video content, and the relationship between the event performer and the identified audience members. For example, based on the event analysis module 80 determining that the event is an awards ceremony, the participant identification module 82 identifying the event performer and the identified audience members, and the participant relationship module 84 determining the relationship between the event performer and the identified audience members, the participant identification module 82 analyzes and the video content to determine actions of the identified audience members at the moment the award is presented. The actions may include, but are not limited to, facial expressions (e.g., smiling, frowning, disinterested, etc.) and/or physical gestures (e.g., clapping, waving, etc.).

In embodiments, the video correlation module 86 is configured to correlate the video content of the actions of the event performer and the actions of the identified audience members in a specified moment of the event. For example, based on the event analysis module 80 determining that the event is an awards ceremony and the participant identification module 82 identifying the actions of the event performer and the actions of the identified audience members at a moment in the event, the video correlation module 86 may correlate the video content of the actions of the event performer when receiving the award to the video content of the actions of the identified audience members when the presentation of the award occurs. For example, the video correlation module 86 may correlate the video content of facial reactions and body gestures of the identified audience members at the moment of the presentation of the award to the event performer. For example, based on determining that the determined moment occurs at time “x” (e.g., the event performer receives an award at time “x”), the video correlation module 86 tags portions of the video content of the event performer at time “x” and also tags portions of the video content of the identified audience members at time “x”. In this manner, the actions of the identified audience members are correlated to the action of the event performer at the identified moment.

The video overlay module 88 is configured to overlay the video content of the actions of the event performer in the specified moment to the video content of the actions of the audience member in the specified moment based on the correlation by the video correlation module 86. In other aspects, the video overlay module is configured to generate a video still image after the overlay of the video content of the event performer to the video content of the audience member at the specified moment. The video still image is a composite image of the event performer and the audience member. For example, based on the video correlation module 86 correlating the video content of captures facial reactions and body gestures of the audience member at the moment of the presentation of the award to the event performer during an awards ceremony, the video overlay module 88 overlays the video frame image of a moment of the clapping of a family member of the audience member with the video frame image of the actual award presentation to the event performer and generates a composite video still image of both the event performer and the audience member.

In another aspect, the video correlation module 86 is configured to rank the identified audience members based on a determined relationship strength of the social relationship between the respective audience members to the event performer. In embodiments, the relationship strength between a respective audience member and the event performer is determined based on the social network data from the social network sites 98 of the event performer. For example, the relationship strength may be based on tags, comments, or posts associated with photos in which the audience member appears on one or more of the social network sites 98 of the event performer.

The system may identify plural audience members that have a social network relationship with the event performer, and the system may determine a different respective relationship strength for each identified audience member. The video overlay module 88 may be configured with a setting that defines a maximum number of images of audience members that can be included in the video still image. In situations where the number of identified audience members exceeds the maximum number of images of audience members that can be included in the video still image, the video overlay module 88 may be configured to select a subset of the identified audience members to include in the video still image based on the determined relationships strengths. For example, if six audience members are identified as having a relationship to the event performer and there is a maximum number of four images of audience members in the video still image, then the video overlay module 88 selects the four audience members that have the highest relationship strengths among the six identified audience members.

The search module 90 is configured to search the video content based on one or more search parameters included in a search input provided by a user. Search parameters may include, but are not limited to: a specified time range in the video content; type of action by an audience member (e.g., a type of facial expression such as smiling or frowning, or a type of gesture such as clapping); and type of determined social network relationship between an audience member and the event performer. For example, the search module may search the video content of a product launch to search for reaction of the audience member during different segments of the video content of the product launch, such as searching the segment in the video content for the reaction of the audience member during the presentation of new products or features of the product. In another example, the search module 90 may search the video content for a search of the audience member clapping hands during the presentation of the award. In another example, the search module 90 may search the video content based on the name of the audience member or the relationship of the audience member to the event performer. For example, the parameter may include identifying the number of class teachers are reacting during the presentation of the award to the event performer.

In accordance with aspects of the invention, based on the search module 90 searching the video content based on the parameter, the video overlay module 88 may utilize the results of the search of the video content to overlay the video content of action of the event performer with the reaction of the audience member to generate the composite image of the event performer and the audience member for the specified parameter.

The search module 90 may be similar to the I/O interface 22 and is a software product that provides an interface between a user of event processing device 60 and the modules 62, 80, 82, 84, 86, 88, and 90. A user interface, such as I/O interface 22, refers to the information (such as graphic, text, and sound) a program presents to a user and the control sequences the user employs to search for the video content by the search module 90. In one embodiment, the I/O interface 22 is a graphical user interface (GUI).

FIG. 3 shows an example of video capturing of the event performance in accordance with aspects of the invention. In FIG. 3, an event performer 315 gives a presentation to members of an audience 340. Camera 310 records the actions of the event performer 315 during the event, e.g., in a field of view defined by the lines AA.
